Figure 9 Reserved internal network configuration
If servers placed on a non-routable network will need to communicate with hosts on the
Internet for any reason (such as performing DNS resolution or sending email), you need to
configure Equalizer to perform outbound NAT (network address translation). When
outbound NAT is enabled, Equalizer translates connections originating from the servers
on the reserved network so that external hosts won't see packets originating from non-
routable addresses. If you're using a Failover configuration, outbound NAT must be
enabled on both Equalizers. For more information, see "Setting up a Failover
Configuration" on page 51.
Note – Due to the additional overhead introduced by enabling outbound NAT, using reserved
internal networks should be approached with caution.
